DataRepeater Glitch when control displays more items than visible

Hi team,

I found an issue present in Wisej.NET 4.0.11 related to DataRepeater.

When the control contains more items than the visible area can display, scrolling to the lower items causes a glitch/flicker and it becomes impossible to properly reach the last elements.

I created a small test application where the issue happens with a DataRepeater containing 50 items added by code.

I tested the control in two scenarios:

1. DataRepeater placed directly on a Form
2. DataRepeater encapsulated inside a UserControl

The issue occurs in both cases.

I started testing older Wisej versions and rolled back step by step until version 4.0.7, where the DataRepeater behaves correctly and scrolling works as expected.

Environment

• Wisej.NET 4.0.11
• .NET 10
• Visual Studio 2026

I’m attaching sample code and a video showing the issue.

Please let me know if this is already fixed for the next release.

Regards, and thanks.
Paul
